Apache ProxyPass 删除 Authorization header

Question

我在一些后端服务器前面设置了一个 Apache 服务器作为反向代理。其中一台后端服务器需要基本身份验证，但 Apache 似乎以某种方式从请求中删除了 Authorization header 。

我是否必须配置一些特殊的东西才能让 Apache 将 Authorization header 传递给后端服务器？

我的 Apache 配置非常基本。我只添加了一些代理指令，例如:

ProxyRequests Off
ProxyPass /backend-server https://backend.server

SSLProxyEngine on

您必须设置 proxy-chain-auth环境变量:

If the proxy requires authentication, it will read and consume the proxy authentication credentials sent by the client. With proxy-chain-auth it will also forward the credentials to the next proxy in the chain. This may be necessary if you have a chain of proxies that share authentication information. Security Warning: Do not set this unless you know you need it, as it forwards sensitive information!
